Explore how adding positive and negative numbers effect your position on a number line! This is an introductory activity that allows students to practice adding integers on a number line. It also allows them to practice comparing integer values!
Materials needed: Bertie Bott's Beans (sold on Amazon), mini dixie cups, mini water bottles (or cups of water), cup that is NOT clear to hold beans, pencil
1) Introduction: Welcome students to Fear Factor (integer addition). Talk up how we will be taking an academic risk today - exploring integers with jelly beans! These are no ordinary jelly beans! The flavors range from delicious marshmallow to gross vomit!
2) Group students and select taste-testers: Take a class poll to determine your class taste testers. Break up your students as you see appropriate.
- -I have a small group of 10, and 5 of my students volunteered to be a taster - so I decided to have my students work in partners. One tester and one recorder.
3) Graphic Organizer: Pass out graphic organizer to each student. Each student will need their own graphic organizer to answer the independent reflection questions at the end.
4) Model: Run through filling out the table on the first page using the number line if your learners would benefit from this support.
- tasty bean is a +1 change. Move right one on the number line
- gross bean is a -1 change. Move left one on the number line
5) Fear Factor: Pass out a mini water bottle and dixie cup to each taste tester. Explain that they can spit any gross beans out into the dixie cup if they have to. They can also drink the water during Fear Factor. Have each tester take one jelly bean out of the cup. Have all testers taste their beans at the same time. Give time after each trial for students to fill in the table on page 1.
6) Class Refection: Complete this page as a class using taster data.
7) Independent Reflection: Students complete this page independently using the data from their taster.
8) Certificate: Certificates can be rewarded to all students who participated in the taste-testing at the end of class.
